Sheep + sheep + sheep= 45

    ?     +     ?     +    ?    = 45

45/3= 15

So, 1 sheep is 15

Sheep+castle+ castle=21

15      +    ?    +   ?     = 21

21-15=6

6/2= 3

So 1 castle tower is 1 point 

Castle + candles=7

3         + ?          =7

7-3=4

So 3 candles are 3 points and 4 candles are 4 points.

Final- 

Candle +sheep+ castle=?

3          + 15    +    2     =20

So the answer is 20
